ASEE 2015: Paper about the new HCDD major

It feels like I just returned from the annual ASEE meeting. I presented a paper about a topic near and dear to my heart: the new undergraduate major in Human-Centered Design and Development (HCDD) I spearheaded at Purdue.

The paper tells the design story (birth story) of the new program. I took a user-centered approach to curriculum design, since that’s what I know best. I think one of the most valuable tools that came out of it was the vision persona. And, of course, the program itself. 🙂

The paper is available online (you can read it here) and the slides I used are below.


DIA2 is out of beta!

Screenshot of DIA2 showing multiple toolsI am so pleased that we launched the redesign of  DIA2 and the new homepage this weekend! It’s been a long and fun journey!

DIA2 is a Web application for knowledge mining and visualization of the NSF funding portfolio. Anyone can use it to explore where NSF funding goes, how it’s distributed geographically, across NSF divisions, across topics, and institutions. You can explore collaboration networks of researchers who worked together on proposals, identify who’s well connected in a field, and figure out what NSF programs and program managers have funded research similar to yours.

I’m happy to have been involved with DIA2 since the very beginning, as a co-Principal Investigator (co-PI). I led the UX team for the project. We started with user research to understand user needs, and moved through ideation, wireframing, testing, the whole 9 yards. It’s been very rewarding to hear users say, “This thing reads my mind!” and “I feel it was designed for ME!” Perhaps best of all, DIA2 gave me the opportunity to work with and mentor many talented students. All DIA2 “employees” have been students working under a PI’s supervision. I am so proud of them!

If you’d like to, go check DIA2 out for yourself – it’s available for all at DIA2.org.

Which self?

I recently watched this TED talk by Daniel Kahneman about the experiencing self and the remembering self.

Apparently, they’re quite different. The experiencing self is the one who lives and feels in the moment. The remembering self is the one that engages in retrospective sense-making and decides, post-facto, whether the experience was good, fun, etc. It is the remembering self’s evaluation that informs future decision making.

This has enormous implications for UX evaluation. Even if the experiencing self has a (relatively) bad time, as Kahneman explains in the talk, but the remembering self makes a positive evaluation, the experience is remembered as good. We can measure UX in the moment, and track eye gaze and all that jazz. But ultimately, what really matters for future decisions is what users take away from the experience and how they evaluate it after it’s over. This is good news. It means that users may forget or put up with a few frustrations – and still assess the experience well, especially if it ends well. It also means that the research framework for website experience analysis that I created back in 2004 is valuable, because it focuses on how users make sense of the experience and what they take away.

Undergraduate UX-related courses

I get this question a lot from undergraduate students interested in pursuing careers in user experience (UX):

If I want to pursue a career in UX, what kinds of courses should I take to prepare?

In addition to courses about user centered design (i.e. CGT 256 and possibly other new courses coming up in CGT at Purdue), it would help tremendously if you learn a bit of any combination from the disciplines below:

  1. programming – especially front end (e.g. CGT 141, 353, 356)
  2. human behavior – any courses that help you understand cognitive psychology: how people learn, how they process information, what gets their attention (visual attention), what motivates them, how they make decisions, how they communicate, how to communicate effectively with them, how to research human behavior – aka research methods in social science, especially qualitative, such as interviewing and observation (at Purdue, for example, PSY 121, PSY 200, PSY 240, PSY 285, COM 318, COM 307)
  3. business and marketing – it is important to understand how a digital product, say a company’s website, is related to the company’s business goals. For that, a bit of knowledge in business and marketing or entrepreneurship is very useful.

Website Experience Analysis

This post explains an alternative research protocol, website experience analysis (WEA).

Website experience analysis is a research protocol (set of procedures) that can help researchers identify what specific interface elements users associate with particular interpretations.

WEA focuses on the messages that users take-away from their experience with the interface.

All interfaces try to communicate something, such as:

  • you should trust this application with your credit card data
  • you should come study for a MS degree in CGT at Purdue
  • etc.

WEA allows you to find out:

  1. whether the interface actually communicates this message – do people actually take away the message that you intended, and to what extent?
  2. what specific elements of the interface users associate with those particular messages (trust, CGT is a good program, etc.)

The WEA questionnaire is based on prominence-interpretation theory. It works with pairs of items that ask:

  1. Ratings of user perceptions (e.g. trust – on a scale of 1-10)
  2. Open-ended: what about the interface makes the user feel this way?

WEA is based on a much more complex theoretical framework of the website experience. The framework breaks the website experience down into two major dimensions: time and space. WEA then explains the phases of the experience as they unfold across time, and the elements of the website space (elements are categorized according to element functions). The theoretical framework is likely only valid for websites, because the experience with another type of interface, even though it may have the same three main temporal phases (first impression, engagement, exit) will likely differ in terms of the steps within those phases and the nature of the spatial elements and their functions.

WEA is different from a regular questionnaire because it connects perceptions with specific interface elements. Questionnaires will tell you whether the user trusts the product, but they won’t provide specific feedback as to what particular elements may account for that perception.

WEA is modular, which means that a different battery of items can be used, depending on the focus of the research. I used WEA in 2 contexts:

  1. To evaluate the experience of visiting organizational websites. Here, I used the 5 dimensions of good relationships between organizations and their publics: trust, commitment, investment, dialog, etc.
  2. To evaluate whether emergency preparedness websites persuade users to take emergency preparedness actions. Here I used a battery of items derived from a theory of fear appeals (EPPM) and assessed whether users perceived there is a threat, believe they can do something about it, believe the recommended actions would be effective, etc.

I think WEA would provide excellent feedback about how prospective students perceive the CGT department, based on their experience with the website. It would be very valuable to find out exactly what about the website makes them feel that:

  • they would benefit from a CGT MS
  • they would fit in
  • they would have a good educational experience
  • etc. – we have to determine the relevant set of items. Ideally, we would have a theory to guide item development.

WEA can be used with other research questions, such as: How do HR managers look at job candidates’ online information? (hello, Jack!)

WEA can be improved upon to better tap into emotional aspects of the user experience. It can be modified to be a more inductive approach, that elicits emotions and interpretations from users rather than asking about specific interpretations (such as trust, etc.)  – thank you, Emma, for these suggestions!

If you would like to read more about WEA, you can find the relevant citations in Google Scholar. I can provide copies of the papers if you don’t have access to them.

Comments on Mac OS X Lion

The actual title of this post is “A couple of things I hate about OS X Lion.”

So, what’s the big improvement in Mac OS X Lion? What does it enable users to do that they couldn’t do before?

In terms of interface, it seems to be a political, not user-oriented movement. The interface decisions say to me: “we’re moving laptops towards touch-screen interfaces.” It may be a strategic step in the next direction for the company. But does it work for the user?

The biggest, and, pardon my French, stupidest mistake/bad idea in Lion is “natural scrolling.” By “natural scrolling” they mean reversing the scroll direction, so now you scroll up if you want to go down a page. Why is this stupid? Let me count the ways:

  1. It takes a behavior that is so ingrained, for some people, since birth – for others, since they started using mice in the early ’70s – a behavior that’s more than second nature, it is automated and memorized by the body and it attempts to reverse it. Good luck with that. After trying natural scrolling for a bit, I got so confused, I don’t know which way is up or down. Good thing you can turn it off.
  2. It takes a behavior that is indeed natural in a touch-screen device when you interact directly with the content, not with the scroll bar and imports it to another, very different device. Just because this behavior is natural on the iPad, where you are touching the page, not the scrollbar, it does not make it so on the computer interface – where design conventions are different, and scroll bars still exist, even if Safari won’t display them.
  3. It forgets that people interact with computers via mice, not only track pads. Don’t get me wrong, I love the track pad. I love the feel of it and the way it works. It’s just that after using it for 6 months without a mouse, my hand hurts so badly, sometimes I think I broke a bone (or more). So I can’t use the track pad, because it literally hurts my hand. I use a mouse. Where scrolling behavior is so automatic (see #1) that all of us are too old to learn a new trick. And where scrolling up is a much more difficult, inconvenient, painful gesture than scrolling down. So, when using a mouse, this natural scrolling is bad, bad, bad for the 3 reasons named before.

Good news: you can turn it off. System Preferences > Trackpad > Scroll & Zoom

What else does Lion do, besides trying to persuade me my MacBook Pro is an iPad?

The Mail interface is much better now, and I can begin to tolerate it – because it looks more like Outlook, which is the only Microsoft product I like. BUT.

They added these silly, annoying animations that are a complete waste of time and, after you’ve seen them once, become a plague. When replying to an email, upon hitting the reply button, the email message I’m replying to does this little dance. It hops out of its place, floats to the top right of the screen, then it settles down in front of me and only then can I begin to type. Cute, the first time. Completely unecessary annoying waste of time after that. Life’s too short to watch email messages dancing on the screen a hundred times a day. I swear I saw Safari dancing around a bit (or some unnecessary animation) when I started it. I haven’t figured out if or how to turn these off.

iCal is pretty much the same. They moved some buttons around, hopefully based on usability studies. No problem there. But they made it look cheesy. The top bar looks like leather (really?!) and it has little marks where you see you “tore off” the previous page. Really?! Talk about adding unnecessary cutesy stuff. And cutesy is a matter of taste. So if you add it, you must allow people to customize it. But I haven’t figured out a way to do it, and am not sure it is possible. If it is, I shouldn’t have to spend 20 minutes trying to find it. Right click, baby. Can we still do that? Oh, wait, two finger tap. Why is that wrong about iCal?

  1. Things that pretend to be what they’re not are tacky. That is not leather. I don’t want it to look like leather. In fact, I don’t really want it to get my attention.
  2. Many people hate leather.
  3. Many people hate that ugly color they chose for the “leather”
  4. The paper calendar metaphor hurts computer-based calendars by imposing on them paper-based page limitations. Cooper wrote about that a long time ago (see pp 37-38). I wonder why nobody listens?

I’m also experiencing some erratic behaviors, like random windows being brought to the front when I select an email address in the To field in Mail… but I assume those were not intended as a way to add excitement to users’ lives.

Tell me, what do you love/hate about Lion?

Natural user interfaces, movement, and emotion (Google Talk)

A Purdue ENE student posted this video on Facebook, and after watching, I had to curate it here. The idea is so simple, and so brilliant – after seeing the video, all I can say is “duh! – it makes perfect sense!”

Here’s the brief summary:

  • we have the technology to interface with computers using movement – aka Natural User Interfaces (NUI) – like Xbox Kinect.
  • movement of the body is related to emotion – something yogis have known for a long time, and modern research is confirming. For example, an open, expansive, body posture will make you feel happy and powerful (see, for example, this research study). Also, body posture and movement have social implications – for example, moving in sync creates liking & trust.
  • Therefore, we should create interfaces that invite open, expansive, fluid body movements, in order to increase positive affect (put people in a good mood).
  • Possible applications: Gmail TaiChi – Using TaiChi movements to sort through your Inbox in the morning; OR: A serious game for learning math that requires open, expansive movement is likely to reduce math anxiety.
  • DUH! Brilliant!
